1209-68-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1209-68-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1209-68:
(6*1)+(5*2)+(4*0)+(3*9)+(2*6)+(1*8)=63
63 % 10 = 3
So 1209-68-3 is a valid CAS Registry Number.

Vinyltin acetals in terpenic and nor-terpenic synthesis

Launay, Valerie,Beaudet, Isabelle,Quintard, Jean-Paul

, p. 937 - 946 (2007/10/03)

Vinyltin acetals obtained by stannylmetallation of homopropargyl acetals with Bu3SnMgMe/CuCN (E configuration) or by titanation of the corresponding alkyltin acetals (Z configuration) have been proved to be efficient storable precursors for the stereoselective synthesis of terpenoids, under mild experimental conditions.Due to the presence of a nucleophilic centre (Csp2-Sn bond) and of a protected electrophilic centre, they are also useful intermediates for an iterative synthesis of retinal and nor-retinoids. - Keywords: vinyltin; acetal; vinyllithium; monoterpenoid; retinal; nor-retinoid
